.uno/m, it' mcg/concern wn that l, Tnovtns R. Sronroos,

n of the. nited lStates, residing at own, in the county of Clear Creek fotate of Colorado, have invented cernew and useful improvements in Vacuum-Cleaners, of which the following is specication. Y

This invention relates to improvements in it@ carpeL sweepers and more particularly to the d J A, lrnown as vacuum cleaners.

@ne object of the invention is to provide a vacuum cleaner which is vsimple in construction, cheap toA manufacture and easily operated.

Another object of the invention is to provide a pneumatic carpet cleaner which may l i dmv-'1. across the floor and the ually operated.

is to improve the suction vapparatus and dust receptacle.

s and advantages will be apie following description, and understood that changes in the c structure shown and described may e made .within the scope of the claims without departing from the. spirit of the inven-l tieni? in the drawings: Figure 1 is a side elevationof the-device. Fig. 2 is a front elevation of the same. Fig. 3 is a top plan view. Fig. l isa vertical longitudinal section vn the line 4 4 o'flfig. 3. vertical transverse section on the 5 5 of Fig. 1. Fig. 6 is an enlarged seeq ti nal view of the valve in the suction pipe. ng particularly to the drav Ylgs., comprises a bellows 1G having bottoni boards 11 and l2.

weon the boards,v and secured ie usual bellows covering; 13. s 11 and 12 are hingedly connect smaller end of the 'bellows by tile leather hinge 14C. ln the board a suitable distance from the hinge v 15 closed from without by glited flap vali/'o16 through v is exhausted from the bellows. i. uitable point in the board 11 and forwardly of the valve 16 is a dust inlet opening 17 connected to which is a dust carrying pipe 1S connected to the suction nozzle 19to he later described. At a point opposite the opening 17 andforined through tne bottoni board 12 is an opening 20 somewhat larger in diameter than the opening 17, which is closed by a hinged door 21 suitably held in closed position by the `hook 22. Between the openings 17 and 20, is a dustcollootingl sack 23, the opposite ends of which are open and have the respective marginal edges 24 secured around the openings 17 and 20. Secured in the under face of the top 'board lland in circular series around the of the bottoni board 12. rEhe normal position of this spring` in contracted position holds the bellows closed. The suction nozzle 19, above referred to comprises a transver-self,7 slotted bottom portion 29 formed integrally` with which, and on which `said nozzle is adapted to slide are'the runners 30. Extending upwardly and rearwardly from the portion 29 is a hollow chambered portion which gradually reduces itself to form the neel: 31 at its upper end. Formed integrally on the neclr is a vertically eX- te ding annular flange- 32 between which and the upwardly extending portion 33 of neclr 3l is an annular channel 34 in which is adapted to rest the lower end of the pipe V13, which may be secured to said ange by any -suitable means as the set screw rl`he inner edge of thev portion 33 is beveled to provide a seat for the ball valve 36, and in thepipe at a suitable distance above the valve seat is a transversely arranged pin 37 to prevent the ball being .sucked up through the pipe 18 during the operation of the device'.v To the lower board 12 of the bellows and adjacent its rear end is secured a handle 38 by means of which.

the device is operated.

- The operation of the device. may be briefly described as follows: The handle of the device is grasped and the nozzle 19 pressed' against the carpet. The device is drawn towardthe operator in the same manner employed'in the' use .of the ordinary rake or to cause the bellows to open and close.

'U )on Dressing down the bellows will o )en against the force yof the spring 27 and draw into the. dust sack 23 dirt laden ain/and upon release, the spring 27 will draw the bellows closed and exhaust the air through the opening l5, the force being snflicient to raise the Hap valve 1G. lhen it is desired to empty the dirt from the sack, the 'door 21 is opened, when the dust and dirt will readily fall out. i y

From the foregoing it will readily be seen that I have provided a simple device of this character which may be easily operated.

-The action being similar to that ofraking,

drawing lthe nozzleacross the carpet and at the same time sucking in the dust.

vWhat is claimed is:

l. In a vacuum cleaner, a bellows including a pair ofk hinged leaves one of which is provided with a dust inlet, a nozzle adapted to contact with the surface to be cleaned? a pipe rigidly connecting the nozzle and the dust inlet, means for holding the bellows normally in closed position, and a handle rigidly secured to the other leaf and extending from the hinged end whereby when the nozzle -is drawn over the surface to be cleaned and downward pressure exerted on the hanrigidly secured to the upper leafgand communicating at one end with the inlet opening, a nozzle connected with the opposite end of the pipe and adapted in the operation of the cleaner to bear against the surface to be cleaned, and a handle rigidly secured to the lower leaf and extending from the hinged end thereof.

In testimony whereof I affix my, signatures inthe presence of two witnesses.
